In carrying the invention into effect, I

have evolved and produced a novel and economical arrangement of parts characterized i by a masonry supported angle or shelf which i adjustable with respect to the compleinental part imbedded in the concrete wall.

I The particular structural features and advantages and their relative arrangement and association will become more readily apparent from the following description anddrawings In the drawings:

Figure 1 is a face View of the part of the structure which is anchored in the wall.

Figure 2 is a horizontal section on the line E2-2 of Figure 1.

' Figure 3 is a perspective view of the adjusting block. m Figure 4 is a central vertical section through the parts assembled. showing the relationship of the angle iron to the anchoring box.

Figure 5 is a horizontal section on the line 55 of Figure t.

Figure 6 is a view showing the device associated with the construction work.

The. relatively stationary part of the device is in the natureof a metallic box which is vertically elongated and of general rectangular configuration, the same being represented by the reference character 7 It is formed in its front with a vertical slot 8 communicating with a vertical guideway 9 for the slidable adjusting block 10. The block and box are substantially wedgeshaped in cross section as seen in Figure 2. The block carries a screw threaded stud 11 adapted to accommodate a retaining nut 12. This stud is intended to pass through an notches 22 accommodate the nails shown). Thenai'ter the concrete is poured 5 this respect the anchoring box constitutes a 1929. fSerial N0. 373,576.

opening in the relatively adjustable parts of the structure which is in the form of an angle iron generally designated at 13. The horizontal flange of this constitutes the so-called shelf. I p 55 The upper portion of the box contains a hanger. plate or partition member 14, which .provides a bearing for the smooth portion of the stem. of the bolt 15. .bolt 16restson this plate and is arranged 60 The head of the in a pocket 17 which accommodates ,a tool or wrenchfor turning the bolt. The threaded portion of the stem is propped into and .througlrthe screw threadedzhole 18 of the adjustableblock shown in detail in Figure 3. (35

It will be observed that the box is formed on opposite sides with outstanding lugs 19 having holes to accommodate the nut equipped and screw threaded portions of the anchoring bail 20. This bail is disposed diagonally with respect to the lug as seen in Flgure 6. The reference characters 21 designate webs for reinforcing purposes. These are. provided with V-shaped nail receiving notches22. Thebox-liire anchor 7 is nailed to the 7 wooden structure of theconcrete form before the concrete is poured... The 'Vshaped (not the bail20 becomes anchored therein'as seen in Figure 6. Also the box is anchored in the concrete. The adjusting bolt 15 is now put in position and threaded through the openings in the adjusting blocks 10. The angle iron 18 is then put in position over the stud 11, in orderto provide asupporting shelf for the masonry facing structure 23, as seen in Figure 6. With this arrangement, the principal feature is the vertical adjustment of the .shelf which permits the proper placement of theinasonry structure. The adjustment may be made by placing the wrench into the pocket 17 and engaging the head 16 of the bolt 15. In

reinforcing andbacking member for the vertical'flange of the angle iron.

It is thought that persons skilled in the art to which theinvention relates will be able to obtain a clear understanding of the Con- 100 mounted for rotation therein, a block adjustably mounted on said bolt, an angle iron support, and means connecting said support with said block through said open front.
